INDIVIDUAL WATER-HEATER.

Specification of Letters Patent.

Patented July 2, 1912.

Application filed March 12, 1910. Serial No. 549,054.

To all whom it may concern Be it known that I, LOUISA B. Rron, a citizenof the United States, and resident of Collinwood, in the county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in Individual l/Vater-Heaters, of which I hereby declarethe following to be a full, clear, and exact description, such as willenable others skilled in the art to which it appertains to make and usethe same.

The objects of the invention are to provide an individual portable formof water heater such that it will be suitable for cott'ages orapartments, and which will include a circulating system and a heatingmeans and will rovide for the necessary warmth and com ort of thetenant, of one room, without the installation of an entire heating plantor equipment throughout an entire building. To accomplish these resultsthe heater comprises a unit or single radiator having provision made forself heating and interior circulation and expansion and consists in thecombination and arrangement of parts as hereinafter described, shown inthe accompanying drawings and specifically pointed out in the claims.

In the accompanying drawings Figure 1 is a perspective View of thedevice; Fig. 2

1s a vertical section from front to rear; Fig.

3 is a horizontal transverse section of the heating drum at the lowerpart of the heater on line mw Fig. 2; Fig. 1 is a perspective view ofthe lower end of one of the outlet pipes.

In these views 1 is a heating drum or circulatin chamber. Inserted inthe upper wall of this chamber are two series of Vertical circulationpipes 2, 2 and 3, 3 respectively, one series of which 2, 2 are longerthan the other series 3, 3. The pipes 2, 2 are preferably in the rearand the plpes 3, 3 preferably in the front of the heater.

The longer pipes 2, 2 extend to the bottom 4 of the chamber 1 and areeach provided with a lateral opening 5, 5, the vertical walls of whichare preferably flared outwardly and extended at 6 to assist in givingfree access thereto for the water in the chamber. The other series ofpipes 3, 3 communicate with the upper part of the chamber only, and thehot water is prevented from entering them by means of a horizontalpartition 7, which joins the pipes 2, 2 above the lateral openings 5, 5.

The pipes 2, 2 are placed closely adjacent to the rear wall 8 of thechamber 1 since it is not intended that the water shall circulate behindthese pipes, or vertical partitions 8, 8, can be placed behind them. One3 of these series of pipes 3, 3, can be made of glass if desired. Thetwo series of pipes extend upwardly and a normal water level ispredetermined and at or about this level substantially horizontal pipes9, 9 connect the front and rear series of pipes.

A heating device such as a gas or gasolene burner or plate 10 is securedunderneath the chamber 1, and the heating means may be connected withany convenient source of gaseous fuel employed in the building or anordinary coal oil burner may be used, since the water does not need tobe heated to the steam generating point.

In operation the water underneath the horizontal partition 7 firstbecomes heated and expanding rises through the pipes 2, 2 and the coolwater in the pipes 3, 3, falls into the upper part of the chamber 1,above the partition 7, and falls between the pipes 2, 2 at 11, 11 so asto become heated to rise again through the pipes 2, 2 to the pipes 3, 3and a constant circulation is maintained so long as the water in thetubes 2 is hotter than the water in the tubes 3 which will be the caseso long as heat is applied to the bottom. Provision is also made for theexpansion of the water if it should become too hot, and for this purposethe pipes 2, 2 and 3, 3 are preferably carried up above the normal waterline and communicate with an expansion chamber 13 in which a higherwater level can be maintained if necessary.

The pipes 2, 2 preferably extend into the chamber 13 to a higher levelthan the pipes 3, 3 and if the circulation through the horizontal pipes9, 9 is not sufficient to take care of the water when expanded, theoverflow from the upper ends of the pipes 2, 2 will do no harm, but willcontinue cooling the water since the higher the elevation the cooler thewater will become.

One of the pipes 3, 3 is preferably formed of glass and a normal waterlevel line L is marked thereon, so that the heater may not contain toomuch water for its capacity to permit expansion. A thermometer T may beattached to prevent overheating and the production of steam. j

Fresh water can be introduced at 14c and the opening can be suppliedwith a closure G which may be perforated to permit air'to enter ifdesired, and to prevent air:.:compression within. An upper cap maybeused to cover the openings.

The device described is also useful for heating water for bathing orother. domestic purposes.

Having described the invention, what I claim as new and desire to secureby Letters Patent, is:

1. In a heater, a heating chamber having an upper wall, and a bottomvertical pipes for upward flow extending upwardly through the upper walland extending downwardly to the bottom and provided with lateralopenings at their lower ends, a transverse partition separating saidheating chamber into upper and lower portions, and extending rearwardlyto said upward flow pipes, the lateral openings in said upward flowpipes communicating with the lower part of said chamber below saidpartition, vertical pipes for downward flow communieating with theportion of said chamber above said partition and communicating with thesaid pipes for upward flow at an elevated point above said chamber, thesaid upper and lower portions of said chamber being in communicationwith each. other around the edge of said partition at pointssubstantially intermediate of the said upward flow pipes.

2. In a hot water heater, a hollow base comprising a heating andcirculation cham-- ber, a horlzontal partition 1n sa1d chamberseparating said chamber into upper and lower portions, means forapplying heat directly to the bottom of said chamber, a series ofvertical upward flow pipes extending to the bottom of the said chamberand provided with lateral openings communicating with the lower portionof said chamber, the walls of said openings turned outwardly, the upperand lower portions of said chamber communicating with each other in therear of said upward flow pipes substantially intermediate of the same,downwardly extending flow pipes communicating with the upper portion ofsaid chamber above said partition, one of said upward flow pipes beingformed of transparent material, and means of communication between theupper ends of said upward and downward flow pipes, said transparent pipeprovided with means for indicating normal water level.

In testimony whereof, I hereunto set my hand this 17th day of February,1910.
